A 1750 N irregular beam is hanging horizontally by its ends from the ceiling by two vertical wires (A and B), each 1. 25 m long and weighing 0. 290 N. The center of gravity of this beam is one-third of the way along the beam from the end where wire A is attached. If you pluck both strings at the same time at the beam, what is the time delay between the arrival of the two pulses at the ceiling
